About this tool
Some tools and platforms insist on PNG: app store assets, print-on-demand shops, certain content management systems, and image editors that only accept lossless input. Converting does not recover detail the JPG already lost, but it gives you a lossless file that will not degrade further with each edit.
About the formats: JPG (JPEG) is a lossy format built for photographs. It compresses aggressively, produces small files, and opens on every device ever made, but it cannot store transparency and each re-save costs a little quality. PNG (Portable Network Graphics) is a lossless image format with full transparency support. It is the standard choice for screenshots, logos, icons, and anything with sharp edges or text, but it produces much larger files than JPG or WebP for photographs.

Questions
Does converting JPG to PNG improve quality?
No. The PNG contains the same pixels as the JPG. What it does is stop any further quality loss when you edit and re-save.
Can I make the background transparent?
Not automatically. This converter preserves the image as-is; use an editor or background remover for transparency.
